Understanding Design Patterns – Inversion of Control / Dependency Injection

Being more of a visual thinker, I prefer understanding and explaining using visuals over words. There are some areas in software development that lack clarity and there is no consensus on 'one correct' definition – such as 'Inversion of Control (IoC)'/'Dependency Injection'. Many of us may have used these patterns in our work without realising it. I wished to know how I used them and have captured 'my version' of what these concepts mean …

Typical Control Flow in a software Program

Inversion of Control Flow

Examples :- JQuery Ajax Calls ; Automated Teller machines

 Examples :- Frameworks like Java Springboot & .NET MVC

Dependency Injection Control Flow

Example : @Values annotation in Java Springboot; DataContext class in .NET
